I you read my first post i have isolated him into his own tank i did that as soon as i saw he was sick. I wasnt sure what to do so i went to the pet shop and found methylene blue it says on the box that it is an anti-fungal agent with antiseptic healing properties and it is effective against a variety of parasites including flukes and is a rapid aid to respiration. My little neon is more active and the redness has gone down a bit, the only problem is he's still gasping for air and still has the pale white patch on his tail but its not a bump any more it looks more like a pale white patch.
